[Coral-List] Sargassum proliferation in Tropical Atlantic

Dear All,

Sargassum is now piling up on the windward (Atlantic) beaches of Tobago and St. Lucia. I was told by a St. Lucian friend that the smell of decomposing Sargassum is overpowering on the southeast coast. Here in Tobago there is even a low level of Sargassum proliferation on the leeward (Caribbean) coast.

Cheers

Dear all, During a scientific expedition from June 19 to July 13, 2017 aboard ANTEA, a ship of the French Oceanographic Fleet, a team of researchers carried out an important sampling of the fauna and flora associated with the « rafts of the Sargassum ». These brown pelagic algae present in the tropical Atlantic have been stranded since 2011 on the Atlantic coasts, because of the ocean circulation. They are responsible for important environmental, health and economic problems, especially in the West Indies and French Guiana. The researchers and teacher-researchers of the IRD, Aix-Marseille University, the University of the West Indies and the University of Western Brittany made a journey of 25 days between French Guiana, the West Indies and the Sargasso sea. Discover their work of locating, sampling and analyzing sargasses, in this film directed by IRD Images.

In Suriname Sargassum started piling on our beaches at the end of March, but it started disappearing again in April (although I understand from fishermen that they are still having some reduced catches due to it getting stuck in their nets). Guyana is currently experiencing Sargassum along their shores, again fishermen are indicting a substantial reduction in catches. So it seems to have moved along our shores from east to west (which is the direction of the Guiana current) from mid-March to now. Last year we had no Sargassum. best Hanneke *Hanneke Van Lavieren* Oceans and Wildlife Coordinator WWF-Guianas Henck Arronstraat 63 Paramaribo, Suriname Tel.: (597) 422357 ext. 115 Fax: (597) 422349 email address: hvanlavieren at wwf.sr visit our website: www.wwfguianas.org [image: Logo] On Wed, May 2, 2018 at 11:00 AM, Mark Tupper wrote: > Dear Ronaldo, > > Flying from Tobago back to Trinidad yesterday there were some > Sargassum mats gathering along the windrows (edges of Langmuir cells) > but there hasn't yet been much accumulation on the beaches.
